3.5. Stainless steel cable trunking
The stainless steel cable trunking is made of 304 stainless steel, with high durability, shiny surface, and durable over time. With stainless steel material, the product is able to withstand high heat and can be used in harsh environments.
Its use is to help lift and install power lines, power cables, and communication cables to become more organized and easier to manage. Currently, the product is widely used by many civil engineering projects across the country.
3.6 . Zam galvanized steel cable trunking
Alloys of Al (aluminum), Zn (zinc), and Mg (Magnesium) with the exact content of Al (6%) and Zn (3%) to improve product durability. It can be said that Zam galvanized steel cable trunking has superior anti-corrosion properties compared to other cable trunkings.
Cable trunkings are made from galvanized steel, Zam corrugated iron is resistant to corrosion of steel materials in environments with many corrosive elements to steel. Ton Zam is covered by a thin coating capable of protecting steel materials better than conventional paint. Therefore, making the product durable, long-lasting, and environmentally friendly.
In addition, Zam galvanized steel cable trunking is plated according to a closed, advanced technical process, heated, and cooled according to a very strict thermal cycle. Bestrunking's Zam zinc corrugated iron always has the characteristics, structure, and product surface uniformity, shine, and outstanding corrosion resistance.
4. Common sizes of cable trunkings
4.1. Cable trunking 200x100
Cable trunking 200x100 (cable trunking 200x100, trunking 200x100) is a commonly used size in construction projects. This product line is usually fixed in technical boxes placed in the house.
Its advantages are small size, easy to transport and install in a small range. Besides, the size 200x100 also has good flexibility of application, reasonable price for civil works and residential areas.
In addition, the materials that make up this electric trough are usually powder-coated, galvanized steel. When choosing to buy this cable trunking, buyers should note that it comes with accessories such as a 200x100 cover, horizontal elbow,...
